What is the net force when forces are balanced?

Back

The net force is zero when forces are balanced.

Front

What is the net force when forces are unbalanced?

Back

The net force is greater than zero when forces are unbalanced.

Front

How do balanced forces affect motion?

Back

Balanced forces do not change the motion of an object; it remains at rest or continues to move at a constant speed.

Front

How do unbalanced forces affect motion?
